Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.
